Here we do a couple of minor fixes like: - Move .ivt section to the very beginning of the image by default which allows us to use that image put right at reset vector (usually 0x0) - Improve relocation fix-up which became required once we moved .ivt and understood a problem with existing implementation where we relied on a particular placement of sections. Now we don't care about placement because we just explicitly check for .text and in case of ARCompact .ivt sections - Re-implemnt do_reset() such that it calls reset_cpu() which could implmented for a particular board And hte most important part we introduce support for yet another devboard from Synopsys - EMDK.

Add support for DEBUG_UART on ARC devboards This required us to do 2 things: 1) Insert a call to debug_uart_init() in early boot code 2) Convert serial_arc to Kconfig Once both items above are done we just patched defconfigs.

Subtle ARC fixes for v2018.05-RC3 These are only very subtle clean-ups here and there including: * Correctly specified CPU freq for HSDK (production boards are all shipped with 500MHZ as opposed to early batch running at 1GHz) * Addition of SNPS internal group email to MAINTAINERS file * Switch to Hush shell on AXS10x boards -

More ARC changes and fixes for v2018.05 * Update of ARC tools to the most recent arc-2017.09 * Fix for compile-time warning for AXS10x * Add support of platform-specific commands for HSDK * Add support for on-board SPI flash on HSDK Note though that for write support another series [1] is required. I hope that Jagan will be able to review and act on SPI flash improvement series before we get beyond RC1. Also note that to get clean build for HSDK we need to disable stack-usage check [2] as our current GCC erroneously tries to calculate stack-usage on a naked function which leads to warning.
